V7 is currently BETA.
If you want to get on the waiting list, fine!
But are you really prepared to deal with all the bugs that Betas can introduce? Then spend more time trouble shooting them?
Yes, you need V7 for MU1 and MU2. It's a 3 month reporting period and you have 6 months. Granted, it would be better to have a full 12 months, but you have all the basics before you, if you have everything in place, 6 months is fine.
Get on the list, don't be in a hurry to be a Beta Tester (unless you really want to be)
